It was the *fastest* code out there which resulted in input buffer overflows when using CCGMS-5.5 as the client terminal. File transfer rates were unaffected when there was no on-screen display. One could easily see the difference between Color 64 at 2400 baud and AABBS at 2400 baud. I imagine AABBS might have run fine using a client terminal in black and white mode. Perhaps it was something to do with the C64 color and graphics set."
